Specification forming part of Letters Patent No. 141,399, dated July 29,1873; application iled April 7, 1873.

the Edges of the Soles of Boots and Shoes, of

which the following is a specification:

Figure l is a plan view of my improved machine, showing the uppersurface of the frame, the boxes for holding the shafts in position, theshafts, and the burnishing-wheels; `and Fig. 2 is a side elevation,showing the frame-work, the drivin g-shaft and pulleys, and a portion ofthe burnishing-wheels.

Corresponding letters denote corresponding parts in both of the figures.

This invention relates to a machine for burnishing the edges of thesoles of boots and shoes; and it consists in providing such machineswith a series of revolving disks or wheels of the proper form, and whichare arranged in such a manner that two or more persons can be employedat the same machine at one and the sa-me time, the construction beingdescribed in that portion of the specification which follows.

ln constructing this type of machines I use a fratrie, A, of peculiarconstruction, its upper end being of the angular form shown in Fig. l inorder that the boxes which support the shafts of the burnishing-wheelsmaybe at about the same distance from said frame, and yet leave eachwheel projecting' beyond the one in rear of it, and thus make itpossible to use. either one of such wheels while any one of the othersis being' used, and while all of the rest are running. This angularframe A is supported upon legs or posts B, which are to be of suchlength as to give the required elevation to the burnishing wheels, theybeing provided with lugs at the proper point for receiving andsupporting a frame, U, in or upon which the boxes which receive thedriving-shaft are'placed. This frame C is similar in form tothe oneabove it in order that it may be attached to all of the legs of themachine, and it has attached to its transverse bars journal-boxes forthe reception of the shaft D, upon which the driving-pulleys Dl and D2are placed, one of them being keyed or otherwise secured to said shaft,while the other is allowed to rotate freely thereon. A belt, from anyprime mover or from another pnlley,rmay be passed over the pulley D1,and thus give motion to all parts of the machine, there being a drum, E,upon tbe shaft D, which turns with it, thus impartingmotion to theshafts ofthe burnishingwheels by means of belts F, as shown in Fig. 2.In the boxes G, upon the angular frame A, there are placed a series ofshafts,

H, each one of which carries upon each ot' its ends a burnishing-wheelor disk, I, 0n the inside of which there is a thin disk of metal, whichis designed to pass in between the sole and the upper of the boot orslice, while the edge ot' the sole is being burnished, for the purposeof preventing any damage to the upper-leather of the shoe. These wheelsor disks, outside of the flanges above referred to, may be of any formupon their peripheries that may be desired, so that they will burnish asole whether its edges are perpendicular, rounded, or beveled. Upon eachof the shafts H a pulley, K, is placed in the proper position to receivea belt, F, which gives motion to said shaft.

Some of the advantages due to this form of construction may beenumerated as follows: First, the machine is compact in form, occupyingbut little room, is cheaper' in first cost than any machine with which Iam acquainted that will do the same amount of work; secondly, two ormore persons can work at the same machine at the same time, and canburnish shoes having different forms of edges to their soles; and, last,by the burnishingwheels or disks, can at anytime be removed forrepairs,A or for the purpose of replacing them without removing theshafts which carry them from their boxes.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The arrangement of the wheels or disks of a sole-burnishing machine, asherein described, as a consequence of which each one projects beyond theone in the rear of it for the purpose of enabling more than one personto work on each end of the machine at one and the same time, as setforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
